Drill deep holes with ultimate control and precision in demanding workpieces using the Phantom 11.900 hss twist drill bit. Featuring a 305 mm overall length and a 210 mm cutting flute length according to din 1869, you easily reach depths standard drill bits cannot manage. This bit is ideal for drilling through thick structural steel sections, hollow profiles, or stacked materials in steel and cast iron. The steam-tempered hss steel effectively reduces cutting friction and improves coolant adhesion to keep the tool cooler during intensive drilling. With its 8 mm cylindrical shank, you benefit from a secure, slip-free grip in standard drill chucks.
